This interactive iOS app follows the design logs of the great Tony Stark from his captive days for Mark I all the way through Mark VI, and gives us a glimpse of what’s to come for Mark VII on the upcoming superhero movie The Avengers.

Marvel’s – and the world’s – most ambitious movie ever, will be hitting theaters this April 25th (PH, with a May 4 opening date State-side). The Avengers is a gathering of heroes who have had individual success – Iron Man, Thor, Captain America. Throw in Hawkeye, Black Widow, the Hulk and the members of S.H.I.E.L.D., plus Thor’s pseudo-brother Loki into the mix, and this is one hot film bonanza to look forward to!
